Oh, Kai Tak, you never cease to amaze me.
The old Kai Tak airport that closed a year before I existed (sadly) would probably be a special mention. Not for the looks of it, but the impact on the surrounding area is actually quite interesting.
Kai Tak was situated right in the heart of Hong Kong, in the Kowloon side of the harbour.
As you can see in that aerial photograph, it's surrounded by development. Planes would often fly ridiculously low over the streets below, and was probably one of the hardest airports to land in at the time.
A scene like this wasn't too uncommon for many people:
Because of the constant aircraft zooming low over the neighborhood, it would be logical that the Hong Kong government imposed a height restriction, which they did. This height restriction lasted up until the airport closed in 1997.
The interesting part is, if you get into tall tower overlooking this specific area, you can guess the age of the buildings. Most of the buildings that are shorter than some 7 or 8 stories have been built before '97.
A major problem in Hong Kong would be the numerous illegal structures built on top of apartments and offices. With that in mind, combined with the restriction at the time drove many people to construct illegal basements under their homes. Practically every building in Kowloon side has at least some sort of illegal underground cellar.
